I will give you my opinion. But please keep in mind it is your tank do as you wish.

I would ditch the red tail shark no matter what, they are nothing but trouble.
Dont be so sure you have a pair on the firemouths just yet, thats a bit young to sex enen by venting.
Jewels in my opinion is what you should be worried about. They could turn anythime and kill off everything in your tank leaving you with one happy jewel.
Blue acaras are tough fish, that is what I use for dithers in my tanks. They could take a beating but do not normally go around looking for trouble. But your tank is 65 gallons right? A full grow blue acara, which is what a 6-7" one is or very close to, will need room and may not tolerate others. It will for sure see 2-3" fish as meals.
